There’S More Than One Way To Climb A Tree: Limb Length And Microhabitat Use In Lizards With Toe Pads, Travis J. Hagey, Scott Hart, Matthew Vickers, Luke J. Harmon, Lin Schwarzkopf

Biology

Ecomorphology links microhabitat and morphology. By comparing ecomorphological associations across clades, we can investigate the extent to which evolution can produce similar solutions in response to similar challenges. While Anolis lizards represent a well-studied example of repeated convergent evolution, very few studies have investigated the ecomorphology of geckos. Similar to anoles, gekkonid lizards have independently evolved adhesive toe pads and many species are scansorial. We quantified gecko and anole limb length and microhabitat use, finding that geckos tend to have shorter limbs than anoles. Combining these measurements with microhabitat observations of geckos in Queensland, Australia, we observed geckos using similar …
